60GHz VCOs with transmission line resonator in a 0.25μm SiGe BiCMOS technology
2008 Edition, June 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, two 60 GHz LC-VCOs are compared. The varactorless oscillators are identical except for the implementation of the inductors. One oscillator uses a traditional spiral inductor, the other oscillator uses a shorted transmission line as inductor....

Microwave Voltage-Controlled Oscillator with Harmonic-Suppressed Stepped-Impedance Resonator Filter
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper proposes a new low phase-noise microwave voltage-controlled oscillator (VCO) with a harmonic-suppressed stepped-impedance resonator (SIR) filter. Since the filter is synthesized by multiple resonators, it can provide a high quality factor...

A phase noise improvement of 19 GHz VCO with use of feedback coupled-line resonator
2015 Edition, September 1, 2015 - European Microwave Association

A phase noise improvement of VCO using a novel feedback coupled-line (FBCL) resonator is presented. The Q factor of the FBCL resonator we propose is 2 times higher than that of conventional simple micro-strip line (MSL) resonators, because the...

A -192.7-dBc/Hz FoM KU-Band VCO Using a DGS Resonator With a High-Band Transmission Pole in 0.18-μm CMOS Technology
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter presents the improvement of the phase noise (PN) of a voltage-controlled oscillator (VCO) by using a defected ground structure (DGS) resonator with a high-band transmission pole. The proposed DGS resonator has two loops in...

Broadband double-balanced SiGe BiCMOS mixer with integrated asymmetric baluns
2017 Edition, November 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A MMIC passive double-balanced mixer (DBM) with on-chip integrated baluns based on 0.25 μm SiGe BiCMOS technology is presented. A mixer core of DBM has been designed using resistive-FET topology. The construction of integrated baluns is broadside-coupled...

Standing-wave transmission-line-resonator VCO for E-band Applications
2011 Edition, April 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, a fully integrated 42-GHz VCO in 90 nm CMOS is described. This VCO is designed for use in licensed E-band (i.e., 81-86 GHz) transceiver systems. In contrast to conventional LC-VCO topologies, a standing wave...

A G-Band Standing-Wave Push–Push VCO Using a Transmission-Line Resonator
2015 Edition, Volume 63, March 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose a standing-wave push-push voltage-controlled oscillator (VCO) using a transmission-line (TL) resonator that covers a frequency range of 151-174 GHz. By properly distributing negative gm cells in the TL...

“Visual” Design of K-band Low-Noise Amplifier Using SiGe BiCMOS Technology
2019 Edition, November 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The decomposition synthesis method (DSM) and "visual" technique for the exact design of microwave low-noise amplifiers (LNAs) based on ideal passive elements are briefly described. In order to account for the losses in real silicon-based MMIC passive elements, more strict constraints...

Transmission Lines Terminated With LC Resonators for Differential Permittivity Sensing
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter presents a differential microwave permittivity sensor based on the reflection coefficient of microstrip lines terminated with series LC resonators. A 50 Ω resistor is considered in series with the resonator. At resonance, the...

A Low Phase Noise VCO Based on Substrate-Integrated Suspended Line Technology
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter presents a low phase noise voltage-controlled oscillator (VCO) based on substrate-integrated suspended line (SISL) technology. With the proposed SISL technology, high-Q resonators and inductors can be realized to improve the phase noise...
